Hacking the Browser

I made a Chrome extension that lets people leave anonymous notes on any website. Anyone who has the Chrome extension can see the notes. The idea is that it would be fun to randomly find little notes left by people, kind of like a digital version of writing a note in a book for someone to discover. I’m aware that because of the anonymous nature it could potentially attract trolls, but I think it’ll be okay for now with ITP users.
